ABSTRACT:
Internally stiffened composite panels and associated manufacturing methods. In one embodiment, an internally stiffened composite panel includes a first face sheet, a second face sheet offset from the first face sheet, and at least one core portion sandwiched between the first and second face sheets. In one aspect of this embodiment, the composite panel further includes a stiffener disposed between the first and second face sheets adjacent to the core portion. The stiffener can have a first attachment portion attached to the first face sheet, a second attachment portion attached to the second face sheet, and an intermediate portion extending between the first and second attachment portions. In another aspect of this embodiment, one or both of the first and second attachment portions is configured to engage a fastener, such as a blind fastener, for attaching a part to the composite panel.
